The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s-1 (3ҩ, respectively.   Fundamentals and applications of electrowetting: A critical review 期刊论文  OAI收割 REVIEWS OF ADHESION AND ADHESIVES, 2013, 卷号: 1, 期号: 1, 页码: 114-174 作者:  Zhao YP(赵亚溥);  Wang Y(王樱) 收藏  |  浏览/下载：55/0  |  提交时间：2014/02/13 Electrowetting (EW)  electrowetting-on-dielectric (EWOD)  Lippmann-Young (L-Y) equation  curvature effect  elasto-electro-capillarity (EEC)  Lattice Boltzmann method (LBM)  phase-field model  molecular dynamics (MD) simulations  coffee stain ring  electronic display  liquid lens  Micro Total Analysis Systems (μ-TAS)  cell-based digital microfluidics   Structural design of large aperture rectangular mirror for space telescope (EI CONFERENCE) 会议论文  OAI收割 2nd International Conference on Civil Engineering and Transportation, ICCET 2012, October 27, 2012 - October 28, 2012, Guilin, China 作者:  Li Z.;  Li Z. 收藏  |  浏览/下载：43/0  |  提交时间：2013/03/25 Structural design of large aperture mirror is one of the key technologies for space telescope development. To meet the requirements of high stiffness  strength and thermal dimensional stability  some factors such as support scheme  materials selection  lightweight design and flexible support design were taken into account. The three supports location of the mirror was determined according to the modal analytical solution. By adjusting the parameters of flexure hinge  influences of gravity  assembly stress and thermal stress on the mirror were reduced obviously. Finite element analysis (FEA) results indicate that the surface accuracy reach to rms10.2nm and 10.8nm under the gravity along optical axis direction and 5C uniform temperature rise respectively  the fundamental frequency of the mirror component is 268Hz. Dynamics test shows that the first order natural frequency is 256Hz  which shows an error less than 5% compared to FEA results.

Firstly  we build the SD model of soybean industry. Secondly  we optimize soybean security policy simulation dynamic model and simulate the model based on our country specific situation. At last  on the basis of the simulation results  we analyze current domestic soybean industry security situation and provide a method to make suggestions for soybean security policy. 2012 Chinese Assoc of Automati.
